Command Description
The read command can be used to request the current operating status and the used alphabet of the Remote-
SAT interface.
The write command is used to activate the AT command interface of the SIM Application Toolkit in the MC55 and
needs to be issued after every power on. However, removing and inserting the SIM does not affect the activation
status.
SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL
INFORMATION) could be executed without activating Remote-SAT.
Parameter Description
MC55 Remote-SAT interface states
0 RESET
1 OFF
2 IDLE
3 PAC

0 GSM character set
Input of a character requests one byte, e.g. "Y".

To display the 16 bit value of characters represented in UCS2 alphabet a 4 byte
string is required, e.g. "0059" is coding the character "Y". For details please
refer to ISO/IEC 10646.
0 SAT is already used on another instance (logical channel in case of the multi-
plex protocol). Only test and read commands can be used.
1 SAT may be started on this instance via the write version of this command.
SAT profile according to GSM 11.14 [19] .
The profile tells the SIM Application which features (e.g. proactive commands) are supported by the SIM Appli-
cation Toolkit implementation of the MC55.

Note
• To limit the time Remote-SAT is kept in states PAC or WAIT any ongoing (but unanswered) Proactive Com-
mand is automatically aborted after 10 minutes with Terminal Response "ME currently unable to process com-
mand" or "No response from user" if applicable. An URC "Terminate Proactive Command" will be send to the
external application in this case, too.
